6 Claims.

porarily distort the traveler a sufficient amount to allow it to be inserted over the rims of the spinning ring and as a consequence, the traveler is very often damaged or fractured.

Also, in present spinning rings, the traveler must have a degree of softness to provide suffioient resiliency in the traveler to spring enough to pass onto or off the ring. With my improved ring this resiliency in the traveler is not required, hence the traveler can be made much harder and therefore will wear longer than travelers heretofore used.

It is, therefore, an object of this invention to provide a spinning ring which has means embodied for allowing the attachment or removal of'a traveler without distortion of the same or interference with the operation thereof.

It is a further object of this invention to provide a spinning ring having a cutaway portion in the rim thereof to provide a passageway through which the open segment of the traveler is adapted to pass and with means for closing said opening to securely lock the traveler upon the ring.

By providing a spinning ring of this type it will allow the traveler to be constructed from material having a greater degree of hardness thereby increasing the life and durability of the same, because it is necessary for the traveler in the conventional construction to be soft enough to allow it to spring over the flanges or rims of the spinning ring when it is being afiixed or removed therefrom.

Due to the fact that the traveler, associated with this mechanism, is harder and is without the usual resiliency, it cannot be pulled off of the flange of the ring by the yarn when its tension varies. The existing undesirable condition termed travelers flying off is eliminated.

Some of the objects of the invention having been stated other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which:-

Figure 1 is a plan view of a spinning ring constructed in accordance with my invention with a traveler mounted thereon;

(or. 11s 59) Figure 5 is a sectional view taken along the line 55 in Figure 3 and showing a traveler mounted on the ring;

Figure 6 is an enlarged top plan view of a portion of a spinning ring showing a slightly modified form of the invention; l Figure '7 is an elevation of the portion of the ring shown in Figure 6; 3

Figure 8 is an isometric exploded view of a portion of the ring and the spring-pressed dog adapted to be attached thereto; Figure 9 is a plan view of a twisting ring with a traveler mounted thereon showinga slightly modified form of the invention;

Figure 10 is an elevation of Figure 9;

Figure 11 is a view similar to the central pora;

tion of Figure 10 but showing the pivoted closure means in an open position;

Figure 12 is a sectional view taken along line l2-l2 in Figure 11;

Figure 13 is a planview of a portion of a ring '3 showing another slightly modified form;

Figure 14 is an elevation of the portion of the ring shown in Figure 13;

Figure 15 is an isometric exploded view of a portion of the ring with the spring pressed dog adapted to be attached thereto.

Referring more specifically to the drawings, the numeral I0 denotes a spinning ring having upper horizontally disposed flanges II and a suitable collar l2 integral therewith. The collar J2 is 10 adapted to fit down against the upper portion of a ring rail when installed. A traveler I3 is adapted to be mounted on the ring I0, said traveler having its inturned ends projecting. be-

neath the flanges of the ring ID in order that it I may be secured thereon. In this position the traveler is adapted to encircle the ring during a spinning or twisting operation.

The end I3a of the traveler normally contacts the lower surface Ila of the flange H under the tension of the yarn and thus end 4312 of the tray.- eler is thus held out of contact with the lower surface Nb of the flange and therefore any roughness which might occur in the joint between in recess 44a cut in rim 38.

the gap and the closure member will not affect the operation of the traveler.

In order to insert the traveler I3 over the flange I0 without the necessity of bending or distorting the same, a suitable dog I5 is pivoted as at I6 to a flange II. Also at this point a suitable notch or slot II has been cut in the outside flange II in which the dog I5 is adapted to fit after the traveler has been inserted upon the ring for operation.

A recess I8 is cut in the upper flange adjacent the slot I! in which the tongue portion I5a, which is integral with dog I5, is adapted to be inserted. When the portion I5a is inserted within the recess I8 the dog I5 is held in alined position with relation to the flange II in such a man-.

ner that there will be no obstruction to interfere with the movement of the traveler I3. When the dog I5 is in a closed position, namely, in the position shown in Figures 1 and 2, the friction between the recess I8 and the portion I5a holds the same in a closed position. A suitable spring 26 normally contacts the end I5b of the dog. I5 to hold the dog in whatever position it may occupy.

In the form shown in Figures 1 to 5 inclusive, the friction between the parts holds the dog I5 in closed position, and the pressure of spring increases the friction on the end I5 and thus assists in holding the dog in closed position. Even if the dog should accidentally move to open position, the moving traveler would move it to closed position.

Figures 6, 7 and 8 show a slightly modified form of the structure in which a dog having a spring portion 26 integral therewith is adapted to be secured as at 21 to the upper portion of flange I I. Likewise a slot 28 is cut in the upper flange of the ring, said slot having bevelledsurfaces 29 and 30 which are adapted to be normally contacted by bevel surfaces 3| and 32 respectively of dog 25. The resiliency of the spring portion 26 normally holds those bevel surfaces in contact with each other, whereas, when it is desired to insert the traveler I3 or to detach it from the ring, dog 25 is pressed downwardly to the position shown in Figure 7.

Figures 9, 10, 11 and 12 show still another modified form in which a twisting ring 35 having a traveler 36 mounted thereon is provided with the same feature. This ring 35 has a collar 3! integral with the exterior thereof which is adapted to fit down against the ring rail when the ring has been installed. The ring also has an upper rim 38 and a lower rim 39, which rims are adapted to be encircledby the inturned ends of traveler 36. In order to make this ring so that the traveler 36 will be insertable thereon or removable therefrom without bending the same, the upper portion of the ring has a notch 40 cut therein said notch being adapted to accommodate a dog 42 pivoted as at'43 in rim 38. The dog is normally pressed into said notch by means of compression spring 44 which is mounted When the dog is inserted within the slot 46 the bevelled ends 45 and 46 of the dog are adapted to normally contact the bevelled portions 41 and 48 of the slot due to the normal spring pressure exerted by spring 44.

Figures 13, 14 and 15 show still another modified form of the invention in which ring 35 has a notch 50 cut in its rim 38, said notch having bevelled surfaces 5| and 52 against which bevelled surfaces 53 and 54 respectively of dog 55 are adapted to fit. The'dog 55 has a spring portion 56 integral therewith which spring portion is secured to the interior of the rim as at 51. This spring normally holds the dog in bold line position in Figure 13 but when a traveler is inserted or removed the dog is pressed to dotted line position to allow the open segment of the traveler to pass over the remaining portion of the ring.

It is therefore seen that I have provided a ring.

7 with means embodied therein for allowing the insertion of the traveler without springing, bending or distorting the same.

In the drawings and specification there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being set forth in the appended claims.

I claim:
